```NOTE:  In reporting the averages from the test we drop
the lowest scores.  This is because 25% (2 out
of 8) of all scores will eventually be dropped.
In comparing your average with the class average
you need to compare with an average which is
representative of the final average.  Dropping
the lowest scores before reporting the average
is one way of estimating the effect of the
final drops. GBA

Overall averages

95 students took all four tests

for these 95 students

the final HW average is  8.6  points

the final quiz average is  7.6  points

the final test average is 57.4% (45.9 points)

and the overall average is 62.1  points

Note that the overall average includes all students who took
four tests.  The test average is computed by dropping the
lowest MC section and the lowest problem section for each
student (except one section of test 4 must be kept), computing
each student's average, and then computing a global average
for all 76 students.  With this final average, the final grade
scale is

43.4  -  53.6     D
53.7  -  65.8     C
65.9  -  77.7     B

with below 43.4 as E and above 77.7 as A.  The final scale was
selected so as to find gaps in the distribution.  With the scale
as given above the highest E is 42.3, the lowest D is 43.4, the
the highest D is 52.7, the lowest C is 53.7, the highest C is
64.9, the lowest B is 65.9, the highest B is 77.0, and the lowest
A is 77.8.  The smallest gap is 0.8 points between B and A.
Grades were assigned strictly based on this scale. ```You can also view the grades as a text file:
